> **Warning:** As of February 2024, the `author` key is no longer supported by Chrome or the Chrome Web Store. If present, it's silently ignored.

An optional manifest key that takes an object with an "email" key (see the example below). This is the email address of the extension author. When publishing a CRX file to the Chrome Web Store, this string MUST match the email address of the account used to publish the extension.

```json
{
  // ...
  "author": {
    "email": "user@example.com"
  },
  // ...
}
```
